Doc On The Run Podcast

A runner thought he had another ordinary ankle sprain. He could still walk, he checked the Ottawa Ankle Rules on himself, and he concluded that he did not need an X-ray. But almost a week later, the swelling and bruising still were not behaving like his previous ankle sprains - and the X-rays showed that his ankle was actually broken.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why runners can be especially vulnerable to self-diagnosis after an ankle injury, how an athlete's pain tolerance can make a serious injury seem deceptively manageable, and why a clinical decision rule is not the same thing as examining yourself.

In this episode you'll learn:

• Why runners may underestimate the significance of pain after an ankle injury

• What the Ottawa Ankle Rules are actually designed to do

• Why being able to walk does not prove that your ankle is not broken

• How extensive bruising and persistent swelling change the level of concern

• Why a violent inversion-and-eversion mechanism deserves extra attention

• How anchoring bias can make a familiar ankle sprain diagnosis feel more certain than it really is

• When an ankle injury is not following the expected recovery trajectory

• Why objective evaluation matters when an injury simply is not behaving normally

Can a stress fracture actually heal with too much bone?

Yes - and in some runners, that extra bone canbecome a problem of its own.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why a very large bone callus does not always mean a stress fracture is safely healed. He walks through two runner cases: one in which a large callus hid an unstable fracture heading toward nonunion, and another in which prolonged irritation produced a completely healed but excessively thick metatarsal that crowded the surrounding soft tissues.

In this episode you'll learn:

• Why bone callus forms around a stress fracture

• How continued motion can create a deceptively large callus

• Why a big callus can coexist with an unstable fracture or nonunion

• How prolonged irritation can leave a healed bone too thick

• Why excess bone can crowd muscles, nerves, and other soft tissues

• Why simply “running less” may not reduce stress enough

• What pain, bruising, and swelling can tell you about injury severity

• Why measuring improvement matters before you increase activity

Can you still do your race after breaking a toe?

Many runners assume a broken toe automatically means canceling the event. But that's not always true.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler shares a real strategy call with a runner preparing to hike the Tour du Mont Blanc after suffering a displaced fourth toe fracture only one week before departure.

In this episode you'll learn:

• The two complications that can permanently affect future running after a broken toe

• Why pain isn't the only thing you should monitor

• How swelling predicts future problems

• Why shoe stiffness matters more than most runners realize

• How to determine whether your toe is stable enough to test

• Why a broken toe doesn't always mean canceling your race

Have you ever felt guilty about taking a day off during stress fracture recovery?

For many runners, the hardest part of getting back to running isn't the injury itself—it's resisting the urge to complete every planned workout.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler shares a simple mental strategy that can help runners recover faster by changing the way they think about recovery days.

In this episode, you'll learn:

• Why runners often feel guilty about taking a recovery day
• The biggest mental mistake competitive runners make during stress fracture recovery
• How soreness and fatigue can actually become valuable warning signs
• Why your coach wants you close to the injury threshold—but never across it
• The simple mindset shift that can prevent setbacks
• Why "earning" a day off can help you recover faster and race sooner
• How to balance fitness gains with protecting a healing stress fracture

The goal isn't simply working harder.

The goal is getting stronger while protecting your healing bone so you can get back to racing as quickly as possible.

Have you ever felt a strange sensation that seemed like a rubber band squeezing your Achilles tendon, shin, or foot?

It may not be pain…

But it might be one of the earliest warning signs that you're about to make a running injury worse.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler introduces what he calls the "Rubber Band Sign"—a subtle sensation reported by runners with Achilles tendon injuries, tibial stress fractures, and metatarsal stress fractures that may signal increasing stress before significant pain develops.

In this episode, you'll learn:

• What the "Rubber Band Sign" feels like
• Why runners describe it before pain develops
• How it may relate to Achilles tendinosis and stress fractures
• Why swelling around injured tissue may create this sensation
• What to do if you notice it during your return to running
• Why paying attention early may help you avoid a bigger setback

The goal isn't simply recognizing another symptom.

The goal is recognizing an early warning sign before your injury gets worse.

When your doctor recommends surgery, there is one question most runners never ask.

But it may be the most important question of the entire conversation.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why runners should not simply accept a recommendation for surgery without understanding how confident the surgeon is that the procedure will actually get them back to running.

Using a recent second-opinion strategy call with an experienced ultrarunner, Dr. Segler discusses how asking for a "guarantee" isn't really about demanding certainty—it's about understanding your surgeon's confidence, expectations, and reasoning.

In this episode, you'll learn:

• The one question most runners are afraid to ask before surgery
• Why "Can you guarantee I'll get back to running?" is really about confidence, not contracts
• How surgeons think differently about different injuries
• Why vague surgical recommendations should prompt more questions
• How to decide whether surgery truly supports your running goals
• Why reassurance and clarity matter before making a permanent decision

The goal is not simply having surgery.

The goal is choosing the treatment that gives you the best chance of getting back to running.

When is the single most important time during the healing of a metatarsal fracture?

Most runners assume the hardest part is waiting weeks to get back to running.

In reality, the most critical period may be the very first week after the fracture occurs.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why the first seven days after a metatarsal fracture lay the biological foundation for healing, and why seemingly small mistakes during that first week can delay your recovery.

In this episode, you'll learn:

• Why the first week is biologically the most important phase of healing
• What happens during the inflammatory phase after a fracture
• Why bone stability is essential for successful healing
• How movement disrupts the body's repair process
• Why even sleeping without your boot may slow healing during the first week
• How small movements from exercise can delay recovery
• What runners should focus on before worrying about fitness

The goal is not simply surviving the first week.

The goal is creating the strongest possible foundation for the bone to heal so you can get back to running sooner.

If your stress fracture seems to be healing, should you keep repeating the exact same run?

It sounds safe…

But it may actually slow your progress.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why repeating identical runs can prevent a healing stress fracture from adapting and getting stronger.

Using the example of a runner returning from a tibial stress fracture with a race only three and a half months away, Dr. Segler explains why variability—not repetition—is the key to safely rebuilding bone strength.

In this episode, you'll learn:

• Why repeating the exact same run can stall bone remodeling
• Why soreness beginning around mile two matters
• How cumulative fatigue changes the stress on a healing bone
• Why bone adapts to progressive, varied loading—not identical loading
• Different ways to vary your running without increasing injury risk
• How to build fitness while reducing the chance of another setback

The goal is not simply proving you can repeat the same run.

The goal is helping the bone become stronger so you can safely return to racing.

Are you testing your stress fracture every day just to see if it's getting better?

That simple habit may actually be slowing your recovery.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why repeatedly testing a stress fracture—especially by intentionally reproducing pain—can keep you above your healing threshold and delay your return to running.

In this episode you'll learn:

• Why runners naturally want to "check" their injury
• How repeated testing can increase stress on a healing metatarsal
• Why pain-testing is different from progress tracking
• How to identify useful recovery milestones without slowing healing
• The concept of your healing threshold—and why it matters
• A smarter way to monitor recovery while preserving your fitness

If you’ve had multiple fifth metatarsal fractures and you also have osteoporosis, can you still run safely?

Many runners assume the answer is automatically “no.”

But that is not necessarily true.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains how runners with osteoporosis can sometimes continue running safely after stress fractures or fifth metatarsal fractures—as long as they understand the specific risks that may have caused the fractures in the first place.

In this episode, you’ll learn:

• Why osteoporosis increases stress fracture risk
• Why repeated fifth metatarsal fractures may not just be about bone density
• How road slope can overload the fifth metatarsal
• Why biomechanics matter in recurrent fractures
• The difference between healing and remodeling
• Why runners with osteoporosis have to be more vigilant about stress management
• The key questions runners should ask before returning to training

The goal is not simply avoiding fractures.

The goal is staying active without re-injuring the bone.
